Near target systems typically allow for imaging with lower illumination and enjoy greater corneal coverage. However, they are sensitive to focusing adjustments, and facial anatomy may hinder measurement. 2 An example is shown in Figure 4-1. They directly measure the curvature of the cornea and calculate the elevation map using a coordinate system from the curvature data. This requires assumptions about the corneal geometry, however. Elevation is generated by fitting slope data to a predefined mathematical model, which may be spheric, aspheric, or a conical section.
